Abstract

The invention discloses a carbon black colored polyethylene glycol terephthalate color master batch and a preparation method thereof. The color master batch comprises the following raw materials in parts by weight: 6-8 parts of modified carbon black, 40-50 parts of modified polyethylene glycol terephthalate and 3-5 parts of an antistatic synergist, the modified carbon black, the modified polyethylene glycol terephthalate and the antistatic synergist are subjected to hydrolytic condensation under an alkaline condition, so that the modified carbon black and the antistatic synergist are connected to a molecular chain of the modified polyethylene glycol terephthalate, and the modified carbon black and the antistatic synergist can be uniformly dispersed in the modified polyethylene glycol terephthalate; meanwhile, a side chain contains an organosilicone polymerized long chain, the organosilicone polymerized long chain is compounded with the carbon black, so that the mechanical property of the color master batch can be greatly improved, meanwhile, a large number of quaternary ammonium salt structures exist on the surface, a layer of antistatic film can be formed on the surface of the color master batch, and the film is connected with a main chain of a color master batch molecule; the problem that the anti-static film falls off cannot occur.

Description

Technical field [0001] The present invention relates to the field of polymer material preparation technology, specifically to carbon black colored polyethylene terephthalate masterbatches and preparation methods thereof. Background [0002] PET, that is, polyethylene terephthalate, is a crystalline polyester, with excellent mechanical properties, insulation and weather resistance, the scope of application includes fibers, films and engineering plastics, etc., but PET material products in the sunlight will occur aging phenomenon and shorten the service life of PET products, carbon black in addition to the rubber industry is commonly used supplements and reinforcing agents, in the non-rubber industry application is also more and more extensive, PET materials added carbon black, in addition to can be used as a toner, It can also be used as a light stabilizer for absorbing ultraviolet rays, because carbon black has a good physical shielding effect on ultraviolet rays, and can also ab...
